* Add roof surface placement support for items Items (e.g. solar panels) can now be placed on sloped roof surfaces. The placement system computes euler rotation from the roof surface normal so items sit flush on the slope instead of going inside. - Add roofStrategy to placement-strategies with enter/move/click/leave - Wire roof:enter/move/click/leave events in the placement coordinator - Add calculateRoofRotation in placement-math using surface normals - Support full 3D cursor rotation for sloped surfaces - Items on roofs are parented to the level with world-space rotation Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> * fixed conflict * editor: per-door-type floor-plan symbols Render a distinct, static plan symbol for each door type in the registry floor-plan builder (`packages/nodes/src/door/floorplan.ts`), independent of the door's live open/close animation: - single / hinged: fixed 90° swing with a dashed quarter-circle arc - double / french: two mirrored half-width leaves + dashed arcs - folding / bifold: static zigzag accordion (~80% span) on the wall face - sliding: bypass — two overlapping panels on parallel tracks + arrow - pocket: thin white leaf, ~60% closed, sliding into the solid wall - barn: surface-mounted panel parked over the wall, dashed closed-ghost + slide arrow The swing arc is dashed in screen-pixel units (the renderer uses non-scaling-stroke). Symbols are oriented by hingesSide / swingDirection / slideDirection as appropriate. Also includes pre-existing working-tree changes unrelated to the door symbols: group move/rotate transform and box-select tweaks, and a regenerated ifc-converter next-env.d.ts.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * editor: garage and open-doorway floor-plan symbols Extend the per-door-type plan symbols in the registry floor-plan builder (packages/nodes/src/door/floorplan.ts): - open doorway (openingKind === 'opening'): bare gap, no leaf/arc/panel (mirrors the 3D system, which renders only the cutout for openings) - garage sectional: closed leaf + side tracks into the garage + dashed parked ghost at the inner end - garage roll-up: closed leaf + coil barrel (capsule) with a coil hint - garage tilt-up: closed leaf + dashed parked panel + dashed curved up-and-over swing path - gate the swing arc to actual swing doors (hinged/double/french) so other types fall back to the plain footprint Garage mechanisms sit on the interior (door-local -z) side to match the 3D garage builders, independent of swingDirection. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> * arch: enforce layer boundaries — registry dispatch, store relocation, shared helper Three architectural fixes to bring the branch into full compliance: 1. **ceiling-system kind check → CeilingCutCapability** Replace `child.type === 'item'` branch in `ceiling-system` with registry dispatch. Add `CeilingCutCapability` type to `packages/core` registry types, implement `buildCeilingHole` on `itemDefinition`, and rewrite `collectRecessedItemHoles` → `collectCeilingHoles` to dispatch through `nodeRegistry` — viewer never again inspects a node's kind directly. 2. **useAlignmentGuides + useWallSnapIndicator → packages/editor** These stores are editor-only UI (snap beacons, alignment guides). Move them from `packages/core/src/store/` to `packages/editor/src/store/`, re-export from `packages/editor`, and update all 34 consumer files across `packages/editor` and `packages/nodes` to import from `@pascal-app/editor`. 3. **findLevelAncestorId extracted to core** `item-light-system` had a private `resolveNodeLevelId` that duplicated level-ancestor traversal logic. Extract it as `findLevelAncestorId` in `packages/core` (spatial-grid-sync), export it, and replace the local copy. All four packages typecheck cleanly (zero errors). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * chore: fix lint, untrack .claude/launch.json Run bun check --write to clear 8 Biome errors (formatting + import order + one unused import). Untrack .claude/launch.json and add it plus .claude/settings.local.json to .gitignore so local IDE/agent configs stop landing in commits.

IFC → Pascal Converter
A web app that converts IFC building models into Pascal scene-graph JSON and
previews the result in the real @pascal-app/viewer. Drop in an .ifc file
(or pick a bundled example), inspect what was extracted, and download the
JSON to load into the Pascal editor.
⚠️ Early alpha
This converter is in early alpha. IFC is a sprawling, loosely-followed standard and real-world exports vary wildly — so expect rough edges: misplaced or missing elements, walls that default to a fixed height when their geometry can't be read, items skipped entirely, and element types that aren't mapped yet. The output is meant for previewing and iterating, not production.
Contributions very welcome — if you hit a file that converts badly, a sample IFC + a note on what's wrong is hugely helpful, and PRs improving the conversion (better geometry extraction, more element types, edge-case handling) are exactly what this needs. Jump in. 🙏
How it works
@pascal-app/ifc-converter(packages/ifc-converter) — the pure conversion logic. Parses IFC via web-ifc, maps elements onto Pascal node schemas from@pascal-app/core. No DOM, no React.- This app — the UI: drop zone, example picker, element search/filters, the 3D preview, and JSON download.
Develop
bun dev # from this directory, or `turbo run dev` at the repo root
The web-ifc.wasm binary is copied into public/ automatically on
install/dev/build (scripts/copy-web-ifc-wasm.mjs). Large example IFCs are
fetched from a public bucket at runtime; the small ones are committed under
public/test-ifc-files/. Override the bucket with
NEXT_PUBLIC_IFC_EXAMPLES_BASE_URL.
Known limitations (help wanted)
- Plain
IFCWALL(Brep/mapped geometry) falls back to a default height — exact per-wall heights need geometry-AABB extraction. - Items (furniture, etc.) are skipped — Pascal items require a catalog asset.
- Beams have no Pascal node type yet and are skipped.
- Doors/windows are matched to walls by proximity when the IFC omits fill relationships; matching isn't perfect.
- Stairs/roofs are placeholders (bounding box / flat polygon in metadata).
